Dry Grinding VS Wet Grinding - Mineral Processing & Metallurgy
The choice between wet and dry milling is, in general, unimportant in small-scale milling but is a major technical problem when large-scale milling in the metallurgical industries is involved. On purely mechanical grounds it is difficult to see any great difference in fundamental principles between wet and dry milling, since dry milling may be regarded as wet milling with a fluid having the ...

Vale to invest 11 billion reais in dry iron ore processing ...
Dry processing is linked to the quality of the iron ore extracted from mining. In Carajás, as the iron content is already high (above 64%), the ore is only crushed and sieved, so it can be classified by size (granulometry). In Minas Gerais, the average content is 40% iron, contained in rocks known as itabirites.
